Tomasz,
The 
// General - purpose Inverse Fisher Transform function
code in TASC May2004 traders tips uses 
 
ICycle=(e^2*Cycle-1)/(e^2*Cycle+1)
 
This would cause an overflow for Cycle values higher than 44.631 [to 
use 3-decimal accuracy]
For many indices the Cycle values are much higher than this level and 
this makes the proposed formulas inapplicable.
[^NDX CyberCycle, for example, was in the range [-600,400] the last 4 
years and the respective range for Nikkei was [-1200,1073]]
the same is repeated in http://www.amibroker.com/members/traders/05-
2004.html
